Where do you put an earthquake gas shut-off valve?

How does an earthquake shut-off valve work?
A sensor moves when the valve is subjected to a 5.4 magnitude or larger earthquake, releasing the valve float which blocks the line and prevents gas going in to the building. The valve is then manually reset once a safety inspection has been done and you’re sure there are no leaks in the building.

How does a natural gas shut-off valve work?
Excess Flow valves are designed to cut off the flow of gas when they detect a higher flow rating than the allotted maximum flow of the home. If you have a line break, the escaping gas will cause excess flow detectable by the valve, which then immediately shuts off the flow of gas into your house.
